question about reading the multiple channels tiff

[dingxm]

I have a multiple channels tiff and the below is the info about this tiff
=== TIFF directory 0 ===
TIFF Directory at offset 0x8 (8)
Image Width: 14066 Image Length: 13367
Resolution: 1, 1 (unitless)
Bits/Sample: 32
Sample Format: IEEE floating point
Compression Scheme: None
Photometric Interpretation: min-is-black
Samples/Pixel: 1
Rows/Strip: 13367
Planar Configuration: single image plane
ImageDescription: ImageJ=1.11a
images=28
channels=28
hyperstack=true
mode=grayscale
The tiff has 28 channels. I read this tiff using image <- readImage(image.fn[1],all=TRUE).
Image
colorMode : Grayscale
storage.mode : double
dim : 14066 13367
frames.total : 1
frames.render: 1
Only one channel was read. Can you help to solve this issue.
The multiple channels tiff was generated by ImageJ from one qbtiff.

Hi there,

did you manage to solve the problem, or is it still a valid issue?

EBImage reads the image via a call to tiff::readTIFF, which doesn't seem to support more than 4 color channels.

You might want to try RBioFormats which has a better support for multi-channel file formats.

Cheers,
Andrzej
